The Bryozoa generally form a rough hardcuticle (cell, ectocyst) whose aperture can be closed by a cover, andwhich often calcifies. In a similar way the mantle of the Brachiopodasecretes a bivalve shell which is generally calcareous, less frequentlyhorny. This shell of the Brachiopoda (Fig. 125) cannot be comparedwith the similarly bivalved shell of the Mussel (Lamellibranchiata,Cochlidce). The two shell valves of the former are do

Phoronis is a small tubicolous animal, of gregarious habits, which has usually been regarded as related to the G-ephyrea. Its body ends in a plume of ciliated tentacles, which can be pro- truded from its tube, and the anus is on the dorsal side, not far from the mouth. In both these respects it agrees with Ceplialodiscus, but a more striking simi- larity is asserted by Masterman to exist between the latter and Actinotrocha, the larval stage of Plwronis.

The black bar is below the plastic sphere. Numbers at the upper right of each frame are time in seconds from the first frame in the sequence. The sphere approached and contacted the tentacle between 0 and 0.27 s. The hood began to lift at about 0.27 s, with the change in shape of hood evident at 0.32 s. Between 0.27 and 0.32 s the particle was drawn rapidly under the hood. It then moved more slowly toward the mouth whi

Behavioral response of Phoronis pallida larvae to increased concentration of ammonium chloride. Error bars equal one standard devi- ation from the mean and were calculated from 3 replicates of 10 larvae per treatment. Average swimming velocities were 1.25 mm/s for larvae in FSW and 3.92 mm/s for larvae in UCSW. The maximum speed for most larvae exposed to UCSW was about 5.5 mm/s, but a few larvae reached speeds of 7 mm/s. A one-way analysis of variance betwee

RMRMYN7K–. Annales des sciences naturelles. Zoology; Biology. LA TACHYGÉiNÈSE. 257 est réalisée normalement par une rétraction de la paroi du corps dans la région qui se rapproche de l'obstacle, une élongation de cette paroi dans la région qui s'en éloigne. La tachygénèse doit donc amener une croissance plus rapide de cette dernière, qui, pour se loger sous la tunique de la jeune larve, se replie à l'intérieur du corps, et se déploie au moment de la rotation dont elle abrège la durée d'autant. Les Phoronis ne sont pas fixés, mais habitent dans des tubes. Chez les animaux qui vivent dans ces conditions
